But they were just buying assets of Data, not Data itself
Buying the stock of a company for a multiple of book value happens all the time.
Buying an asset should happen at what the asset is worth, not some arbitrary multiple.
If they had bought an asset from an unrelated company for 3 times what it was worth, you could call that misfeasance.
Since they control both sides of the transaction, it becomes something murkier in my eyes.
